4. Discussion
5. Conclusions
- (1)
- SAXS and HRTEM reveal the strong structure heterogeneity at nanometer and tens of nanometer scales, respectively, in the Vit105 alloy compression processed to a reduction of ~64%. Compared to the as-cast alloy, these distinctive heterogeneity features stand for the significant potential of modifying BMG structure through proper deformation processing.
- (2)
- A transition of SRS of stress, from 0.012 in the as-cast specimen to −0.005 in the compression-processed specimen, was observed through nanoindentation, accompanied by the gradual vanish of serration phenomenon in the compression processed samples at the increasing strain rate.
- (3)
- Qualitative mathematical formulation, based on the physics of shear band nucleation-controlled plasticity of BMG, describes the inherent link between the observed negative SRS and the internal stress existing in the materials. It reveals the physical origin of this negative SRS frequently reported in structural heterogeneous BMG alloys and its composites.
